GeForce 8800 GT 512MB vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which has core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M385X should perform quite a bit faster than the GeForce 8800 GT 512MB in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 38400 (67%)

Texel Rate

The Radeon R9 M385X should be much (more or less 83%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 28000 (83%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M385X is superior to the GeForce 8800 GT 512MB, by far. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 8000 (83%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
